Why would Google keep a copy of your mail if your account was deactivated for 6 years? Isn't that asking a bit much considering you were the one that broke the ToS?
At least according to the page I get when I try to log in, they still have the data: https://support.google.com/accounts/answer/40695?hl=en&ctx=c...
I don't disagree that Google was within their right to shutdown my account, but it seems silly that something I did at 19 has gone on this long.
